摘要
Underwater acoustic communication is a rapidly growing research area nowadays and many related studies have already been conducted in recent decades. Underwater acoustic communication can be easily applied to many fields, such as oceanic data collection, undersea exploration, disaster prevention, underwater environmental monitoring, and tactical surveillance. However, there are many challenges associated with underwater communication, including bandwidth limitations, multi-path propagation, padding, long end-to-end propagation delay, high bit error, temporary loss of connectivity, and limited battery power. To overcome these problems, existing implementable MAC protocols need to be classified in terms of network topology. To improve network mobility, two kinds of network topologies, which include cluster-head-based and ad-hoc-based MAC protocols, are considered. In this paper, we summarize some selected MAC protocols and analyze their performance by comparing a number of factors. We obtain experimental results by developing and simulating the existing numerical models of each protocol practically using simulation tools.
